PRINTING-RULE SYSTEM OF APPLYING SAME T0 PRINTING-FORMS.

' Specification of Letters Patent.

' Application filed July 5,1910. Serial NO. 570,333.

skilled in the art to which it appertains to make and use the same.

My invention relates to the art of'molding and composing type by machinery and has special reference to the co-called ruling of type-forms by the application ofseparate rules thereto, and particularly to type forms of the kind produced by linotype and other type casting machines. As will appear hereinafter, my invention is also applicableto the ruling of forms composed of ordinary.

hand set type. I

The primary object of my invention is to provide a ruling system comprising special rules and attaching means, and which. shall reconcile the use of such rules to the dimensions of the type and type slugs produced by type matrices of the shape and depth commonly employed. 1 My invention consists in the combination of a type form which presents or has a substantially level top surface and type rising therefrom, with a ruleresting. O nsaidtop surface and a plurality of projections upon and rising above said top surface and servin to. hold said rule thereon.

ore specifically defined, my invention consists in a rule which rises to the height.

of the type faces, in operative combination witha plurality of parts which are integral with the type form body and engage said rule above said top surface and below the plane of said type faces.

The invention will be more readily understood by reference to the drawings, forming part of this specification and in which; I L

.Figure 1 is a perspective view of a ruled type form-embodying my invention; Fig. 2

.- is a perspective view of one of the linotype slugs shown in Fig. 1, the dotted lines of Fig. 2 being indicative of the fact that my invention is adaptable to lines made up of separate type, as contrasted with a linotype or logotype slug. Fig. 3 is a vertical section on the plane of theline XX of Fig. 1

of which Ordinarily conform to a s' accompanying Patented Nov.- 1, 1910.

clearly showing the position of the rules on the top surface of the type form and the projections on said surface by which the rules are held, some of said projections being shown as they appear when either in-' tentionally or accidentally bent or battered against the rules; Fig. 4 is a similar sectional view showing the projections as they appear when deliberately and uniformly, bent or pressed against the rules to increase their holding or looking effect thereon; Figs. 5, 6,

7 and 8 are enlarged cross-sections showing some of the various shapes in which mynovel rules are made. I

In the drawings 2, 2, represent a plurality of so-called lino-type slugs the upper edges mgle plane 3 and constitute the top surface of the type form. The type, 4, are molded upon and rise fromthis surface being formed at the same time as the body of the slug. Strictly speaking, each type comprises a shoulder 4' and a type proper thereon, and theplane of 'the surface,-3, constitutes the base of the shoulder.- I arrange my rules, 5, directly upon the surface, 3, between the columns of type. thereon. These rules which rest on the surface, 3, are substantially the same height .as the type. It being necessary to secure the rules to the typeform I provide' special metallic fastenings for the-purpose,ysuch fastenings being characterized by the fact that they project upwardly from the surface, 3, andengagethe rules at points above said surface. As indicated in the drawings these metallic fastenings vmay be of several .kinds or shapes. They are formed directly .on the, top surfaces of respective.

type bodies or slugs by the same method which is employed mforming or castmg the type. As 0 triangular or substantially triangular in cross-section, each thereof presenting a broad base to the top .Of the type form and having anarrow upper or ruling edge, preferably. disposed midway above the broad base. The height of the type upon most linotype slugs ranges from thirty to fifty thousandths of an inch and the rules sub-- 7 stantially correspond to this dimension, from which it Wlll be seen that the terms broad and narrow are relative, the differences being barely perceptible to the eye, and the drawings herein are greatly early indicated in Figs. 5 to 8 1 inclusive the rules which I prefer to use are enlarged and indicate maximum differences of dimension between the bases and the printing edges of the rule.

I do not. herein claim my novel rule, aside from its association with the holding means. The rule is so claimed in my co-pending application Serial Number 507,217 filed July 12, 1909.

For fastening, locking or anchoring the rule upon the form, I employ projections 6 which are integral with the type bodies or slugs and are formed in matrices similar to those used in forming the type. I frequently use these integral locking projections in conjunction with the separable anchoring plates 7 or 7' (see Fig. 1) arranged between the slugs and engaging the rules, but quite as often, I dispense with such independent fastenings and utilize only the integral projections. The plates 7 and 7 are fully disclosed and claimed in my said application Serial Number 507,217 and are not claimed herein, except in combinationwith the other fastenings. The integral projections, 6, are in most cases arranged in pairs on the slugs, there being two for each rule and the rule resting upon the top surface, 3, between such lugs; but a single lug or projection will serve the mrpose when the rule is laid directly against a type shoulder, in which case the type takes the place of one lug. It is apparent that by arranging a rule between alternately positioned lugs on the several slugs, I may avoid the necessity for complete pairs at each point, but this is rarely desired. These lugs, (3, may be of various lengths and cross sectional forms suited to the easy draft of the metal from the matrices. Their only important dimension is height, this being always less than the height of the type so that the projections shall not be imprinted upon the paper in the press. The position of the lugs or projections, upon the slugs determines the position with respect thereto of the rule and it is obvious that by molding or positioning the projections upon the form in a predetermined arrangement the rules may be held inany desired position upon the top surface of the form. When linotype slugs provided with such lugs and rules as described, are locked in the chase they will usually be shifted slightly with respect to one another and this movement, together with the unavoidable inaccuracy of alinement of the anchoring projections, insures the retention of the rules. This action, however, need not be and is rarely relied upon to permanently fasten the rules but instead such locking effect is added to by the accidental and also the intentional battering or bending of the projections against the rules, as indicated in the drawings. The metal from which type slugs are cast is relatively soft and I have experlenced no difficulty in battering or bending the lugs upon or against the rule, as well shown in the drawings.

As indicated by the dotted lines in Fig. 2, both kinds of projections here described may be used upon separate spaces or high quads in connection with ordinary single or mono-type. My novel rules and rule holding projections, lugs, or integral anchor parts, as herein suggested, may be made in many different forms, and I desire it to be understood that my invention is not limited or confined to the specific forms, shapes, and arrangements of parts herein shown and described.

llaving thus described my invention, I claim as new and desire to secure by Letters Patent: Y

1. A type form which has a substantially level top surface and type molded upon and rising therefrom, in combination with a rule resting on said top surface and a plurality of 'irojections integral with said top surface of the form, said projectionsrising above said top surface at opposite sides of said rule and engaging said rule to hold the same on said surface, substantially as described.

2. A type form which has-a substantially level top surface and type molded upon and rising therefrom, in combination with a rule resting 'on said form and rising to the heightof said type and a plurality of projections rising from, integral with said top surface, of less height than said type and engaging opposite sides of said rule to hold the same on said surface, substantially as described.
